In terms of income ratio of Samsung, it is so focused on mobile business. Samsung mobile business income may beat rest of all samsung conglomerate incomes. Apple has been the biggest customer for Samsung FAB. As Apple were pulling out, it became like factory without running. Not sure why Apple chose both TSMC and Samsung fabs, may be gaining some bargain power, TSMC is one of the best. Qualcomm takes on the most advanced process with TSMC. AP is designed by apple and they can always choose which fabrication facility to produce. Samsung FAB and mobile business are not in the same boat
